RF Test
-
RF is short for radio frequency. RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation. These frequencies make up part of the electromagnetic radiation spectrum.

Magnetic Resonance Instruments
-
Integrated Dynamics Engineering
MRI systems represent a significant investment. As magnetic resonance images can be distorted by electromagnetic fields, frequently the location is isolated by passive shielding to somewhat insulate the detectors from image distorting EMI. But for a fraction of the cost of the machine an active EMI compensation can fully protect the image from damaging fields generated by other electrical equipment, passing traffic, elevators or other nearby equipment.

RFID tags bring the future of technology to today. Radio-frequency Identification(RFID) tags can be placed on almost any piece of clothing, cash, animals and even humans. Tags use electromagnetic fields to identify and track the desired object. Active tags are powered by a battery located inside the tag, and may operate over hundreds of meters away from the RFID reader. RFID tags have been expanding ever since their inception – they became especially popular when used in toll readers and assembly lines to track the product’s progress throughout the assembly line.

Holland Shielding Systems B.V.
Electromagnetic fields cause interference in electronic devices and may affect the health of people close to where the fields are generated. It is important to recognize this at an early stage in a construction process, for instance at a future construction location or while construction is already underway, so that budgets are not exceeded. By means of field-strength measurements one can chart the existing electromagnetic fields and radiation emitted by GSM, UMTS antennas and transformer spaces, to mention a few examples. These measurements can help determine the best location in the new building for rooms where sensitive measurements are to take place, e.g. in hospitals or nano laboratories. And last but not least, field-strength measurements can detect sources of interference and can be part of a scheduled check of existing screened spaces and Faraday cages.
